index and Match that Sums everything

Alex Klingbeil

i have right now

=INDEX({Project Tracker - By Work Package Range 1}, MATCH([SYSTEM/CABLE]@row, {Project Tracker - By Work Package Range 2}, 0))

this works great but it only comes back with the First number it finds. i need it to Come back with a Sum or Total of all the Numbers it finds.

Sheet i want the info on.

working INdex match formula

sheet all my Data is coming form

High lighted are a double set of Cables that show up. i need the Index and match to no just Read 17. i would like it to Add the 2 17's together and keep adding if more 1076B cables get added to the sheet.

i seen a few topics talk about Join but i cant seem to get that to work.
